VIETNAM IPHONE CHARGER FACTORY - MyMy Technology
In the production of high quality iPhone chargers at MyMy Technology Vietnam iPhone Charger Factory, the coating is not only an external aesthetic factor but also a complex dielectric technology inside the circuit core. This protective coating plays a key role in temperature control, component protection and electrical safety.
This article explores the role and rigorous standards ofCore protective coating – the deciding factor in charger durability and charging performance.
THE SPECIAL ROLE OF THE DIELECTRIC COATING
The core coating (usually Conformal Coating or Epoxy/Silicone Resin) is the final shield that protects the sensitive electronic components.
1. Voltage Performance Stabilization
- Core paint helps stabilize voltage during charging:This insulating dielectric coating covers the transformer coils, capacitors and solder joints. It helps to fix the position of the components, preventing displacement and vibration in high temperature environments. When the components are stable, the capacitance and inductance parameters are maintained accurately, so the circuit canCore paint helps stabilize voltage during charging output, ensuring clean power supply to the device.
- Dielectric coating technology helps reduce power consumption:High-quality insulating paint has a low dielectric loss factor. This minimizes energy loss as heat or electromagnetic interference (EMI) on the circuit board surface. This directly contributes to increasing the charger's conversion efficiency and reducing unnecessary power consumption.
2. Increased Strength and Corrosion Resistance
- Core protective coating – the deciding factor in charger durability:This coating creates a physical and chemical barrier for the entire electrical circuit.
- How to paint the core to protect components from oxidation:Solder joints, component pins and copper on PCB are very susceptible to oxidation, especially in humid environments or tropical climates like Vietnam. Core paint prevents components from contacting with moisture, dirt and corrosive substances, significantly extending the life of the charger.
- Application of chip pin coating technology in charger:The control chips (IC) and fast charging chips are the most complex and expensive components. Special coatings, even Epoxy or Silicon resins at the chip feet (Underfill), help fix them to the circuit board, increasing resistance to thermal shock and mechanical vibration.
ENSURING SAFETY AND INTERNATIONAL STANDARDS
The quality of the core paint layer must comply with theInternational standards for iPhone charger core coating to ensure electrical safety and operating performance.
1. Explosion-Proof Mechanism
- Core paint helps the charger prevent explosion when the voltage increases:In the event of a sudden voltage surge (such as a lightning strike or a power grid fault), the protection circuit kicks in. However, the insulation core coating plays a supporting role, helping to prevent arcing between points of different voltages on the board.
- Core coating thickness testing in charger production:This is an important step inProcess of testing the insulating paint layer in the charger core. The paint thickness must meet technical standards (usually several tens of micrometers) to ensure effective insulation without affecting heat dissipation. Too thin will not insulate enough, too thick will retain heat.
2. Comparison of Coating Materials
In the production of chargers, the two most common materials used to createcore protective coatingare Epoxy and Silicon.

Job Comparison of epoxy core paint and silicone core painthelp manufacturers choose the right material for each area of the charger circuit board (e.g. use Epoxy to secure heavy components, use Silicon to cover heat-resistant circuits).
TREND OF PRODUCING GREEN CHARGER IN VIETNAM
MyMy Technology Vietnam iPhone Charger Factory is gradually shifting to follow the global trend of environmentally friendly production.
- Environmentally friendly core paint – green trend of Vietnamese factories:Modern circuit coatings prioritize the use of paints that do not contain toxic solvents (Non-solvent, Water-based) or UV-cured polymer materials. This helps to minimize the emission of volatile organic compounds (VOCs) during the production process, protect the health of workers and minimize the impact on the environment.
- Effect of core paint on power transmission efficiency:A substandard core coating (e.g., peeling, containing air bubbles) can create electrical accumulation points, causing voltage drops or electromagnetic interference. In contrast, a high-quality core coating ensures dielectric uniformity, which minimizes losses and improves power transmission efficiency from the circuit to the charging port.
In short, core coating technology is an inseparable part of the production process of high-end iPhone chargers. The meticulousness in core coating thickness testing and the choice of materials such as silicone core paint is the key factor, turning the charger not only into a charging device but also a solid protective fortress for the user's mobile device.
